SWIVEL STOOL Filed Oct. 25, 1956 m'll Deg ATTORNEY Patented June 15, 1937 UNITED STATES PATENT OFFICE 3 SWIVEL STOOL Will Frey, Eunice, La. Application October 23, 1936, Serial No. 107,289

3 Claims.

This invention relates to swivel stools, chairs and the like and has for an object to provide novel means for adjusting the stool vertically, said means being more compact, comprising less parts,

and promoting a quicker adjustment of the stool than similar types of adjusting means now in use.

A further object is to provide a swivel stool which will be formed of a few strong simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a side elevation, with parts in section, of a swivel stool constructed in accordance with the invention.

Figure 2 is a cross sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a fragmentary cross sectional view taken on the line 3-3 of Figure 1.

Referring now to the drawing in which like 0 characters of reference designate similar parts in the various views, [0 and II designate superposed substantially square sheet metal plates which are connected by the vertically disposed upper ends l2 of metal legs I3, the lower ends of the legs being inclined outwardly and terminating at the bottom in rings M for engagement with linoleum or other fioor covering without scratching or marring the same.

A post [5 is mounted to slide vertically in openings l6 and I1 formed at the centers of the plates l0 and II. The post is equipped at the lower end with a retaining ball l8 which is provided with a threaded opening to receive a threaded stud I9 projecting axially from the lower end of the post.

The upper end of the post is equipped with a swivel stool seat 20, or chair bottom as desired and for this purpose the upper end of the post is uniformly reduced as shown at 2! and is received in a bushing 22 having a collar 23 which bears upon the shoulder at the bottom of the uniformly reduced portion 2|. A conventional ball bearing assembly 24 surrounds the bushing and is seated on the collar 23. A plate 25 is secured at 55 the bottom of the seat by screws 26 or otherwise and is provided with a flange 21 which houses the ball bearing assembly 24. Thus the seat is swivelly mounted on the post and may be easily moved by virtue of the ball bearing connection of the seat with the post as described.

For adjusting the seat vertically a ring 28 of slightly greater diameter than the post surrounds the post between the plates I0 and H and is equipped with a lever 29 which is loosely fitted in an opening 30 in a vertical bar 3!, best shown in Figure 3, which connects the plates ID and H. The outer end of the lever 29 is equipped with a ball 32. The lever rocks on the lower edge of the opening 30 as a fulcrum when the ball 32 is pushed downward to permit the ring 28 to move upwardly and release its binding action on the post l5 so that the post may slip downwardly to lower the seat.

To raise the seat it is simply necessary to grasp the seat 20 and lift it vertically since the ring 28 will thereby be moved upwardly by frictional engagement with the post until it reaches a point where it releases its binding action on the post and permits the post to move upwardly. Immediately upon the seat 20 being released the weight of the seat causes the post IE to gravitate, the post carrying the ring 28 downwardly with it until a point is reached where the ring again asserts its binding action on the post to lock the post in the adjusted position.

By virtue of having the fulcrum 30 of the lever 29 spaced considerably from the ring 28 the binding and releasing action of the ring will be quick acting while at the same time no springs, pawls, rack teeth, or other devices need to be used to control adjustment of the seat post.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.

What is claimed isi 1. A swivel stool comprising vertically spaced horizontal plates, legs connecting the plates and extending below the plates, a post slidably mounted in aligned openings in the plates, a seat mounted on the upper end of the post, a retaining ball on the lower end of the post, a vertically disposed bar connecting the plates and having an opening therein, and an operating lever extending loosely through said opening and terminating in a ring encircling the post and of slightly greater diameter than the post, the weight of the post and seat causing the ring to exert binding action upon the post, vertical movement of the seat and post rocking the lever on the bottom edge of the openthe support, a. post movable vertically through the support, a seat on the upper end of the post,

a vertically disposed member carried-by the support ing, and a ring on the operating lever encircling the post and of slightly greater diameter than the post, pivotal movement of the lever on sald mem- WILL FREY.
